Exoscale Computer Driver Documentation¶
Exoscale is a public cloud provider based in Switzerland with data centers in Geneva, Switzerland.
Exoscale driver is based on the CloudStack one and uses basic zones. For more information and CloudStack specific documentation, please refer to CloudStack Compute Driver Documentation page.
API Docs¶
- class libcloud.compute.drivers.exoscale.ExoscaleNodeDriver(key, secret=None, secure=True, host=None, path=None, port=None, url=None, *args, **kwargs)[source]¶
Inherits: NodeDriver.__init__
Parameters: - host (str) – The host where the API can be reached. (required)
- path (str) – The path where the API can be reached. (required)
- url (str) – Full URL to the API endpoint. Mutually exclusive with host and path argument.
- attach_volume(node, volume, device=None)¶
@inherits: NodeDriver.attach_volume :type node: CloudStackNode
Return type: bool
- create_key_pair(name, **kwargs)¶
Create a new key pair object.
Parameters: - name (str) – Key pair name.
- name – Name of the keypair (required)
- projectid (str) – An optional project for the ssh key
- domainid (str) – An optional domainId for the ssh key. If the account parameter is used, domainId must also be used.
- account (str) – An optional account for the ssh key. Must be used with domainId.
Returns: Created key pair object.
Return type:
- create_node(**kwargs)¶
Create a new node
@inherits: NodeDriver.create_node
Parameters: - networks (list of CloudStackNetwork) – Optional list of networks to launch the server into.
- ex_keyname (str) – Name of existing keypair
- ex_userdata (str) – String containing user data
- ex_security_groups (list of str) – List of security groups to assign to the node
Return type: CloudStackNode
- create_volume(size, name, location=None, snapshot=None)¶
Creates a data volume Defaults to the first location
- create_volume_snapshot(volume, name)¶
Creates a snapshot of the storage volume.
Return type: VolumeSnapshot
- delete_key_pair(key_pair, **kwargs)¶
Delete an existing key pair.
Parameters: - key_pair (:class`libcloud.compute.base.KeyPair`) – Key pair object.
- projectid (str) – The project associated with keypair
- domainid (str) – The domain ID associated with the keypair
- account (str) – The account associated with the keypair. Must be used with the domainId parameter.
Returns: True of False based on success of Keypair deletion
Return type: bool
- deploy_node(**kwargs)¶
Create a new node, and start deployment.
In order to be able to SSH into a created node access credentials are required.
A user can pass either a NodeAuthPassword or NodeAuthSSHKey to the auth argument. If the create_node implementation supports that kind if credential (as declared in self.features['create_node']) then it is passed on to create_node. Otherwise it is not passed on to create_node and it is only used for authentication.
If the auth parameter is not supplied but the driver declares it supports generates_password then the password returned by create_node will be used to SSH into the server.
Finally, if the ssh_key_file is supplied that key will be used to SSH into the server.
This function may raise a DeploymentException, if a create_node call was successful, but there is a later error (like SSH failing or timing out). This exception includes a Node object which you may want to destroy if incomplete deployments are not desirable.
>>> from libcloud.compute.drivers.dummy import DummyNodeDriver >>> from libcloud.compute.deployment import ScriptDeployment >>> from libcloud.compute.deployment import MultiStepDeployment >>> from libcloud.compute.base import NodeAuthSSHKey >>> driver = DummyNodeDriver(0) >>> key = NodeAuthSSHKey('...') # read from file >>> script = ScriptDeployment("yum -y install emacs strace tcpdump") >>> msd = MultiStepDeployment([key, script]) >>> def d(): ... try: ... driver.deploy_node(deploy=msd) ... except NotImplementedError: ... print ("not implemented for dummy driver") >>> d() not implemented for dummy driver
Deploy node is typically not overridden in subclasses. The existing implementation should be able to handle most such.

- ssh_username (str) – Optional name of the account which is used when connecting to SSH server (default is root)
- ssh_alternate_usernames (list) – Optional list of ssh usernames to try to connect with if using the default one fails
